Amateur Lover: continuing with toys (CV: WasshoiTarou)

[Synopsis]
You are curious about one of the toys that Eiji has yet to use on you.
You wonder what it would feel like... and while reading the manual and reviews
Eiji catches you wet handed! (Just like you wanted him to...)

[Character]
Eiji (30 yo) is an employee at your company, 4 years your senior.
He is serious and square and at first you thought he was too strict but,
it's just that he doesn't let off on his kind, caring and bashful side at work.
He didn't have much experience with the opposite sex until dating you
and still feels embarrassed when involved in a sexual relationship.
Due to his nature, sometimes he can go off on tangents.
